Published by at 10:30 am under Mazda Tutorials

Tools Required:
Drain pan / container

Ratchet

10 MM Socket

3/4 Socket

Pliers (not shown )

4 to 6 feet of clear 3/8th I.D. Hose ( 25 cents/ foot at Lowes) ( not pictured )

1- Drill ( Optional ) Used to remove 10mm bolts faster.

Fluids:

3 to 9 quarts of Mercon V

3 Quarts of Synthetic Mercon V (Optional for last 3 quarts )

Difficulty: 4 / 10

Time Required: 30-45 Min

Install:

Begin by first putting your car up on ramps or on a lift. I used ramps and 2x 2 x 4′s – my car is lowered.

Remove splash guard under car. There will be 7x 10 MM BOLTS Use your ratchet and 10mm socket to remove them.

Locate the drain plug on the back of the transmission pan. This is on the drivers side.

Place a plastic bag behind the transmission and cover your front suspension, this is vital to keep fluids from going everywhere.

Place your drip pan or bucket under the drain bol

Remove the drain plug / Bolt with your 3/4 socket and ratchet, be careful not to loose the metal washer as you remove the bolt.

The fluid will come out very fast.

(optional) Start the car with the break pressed firm, put it into R,N,D and then back to park, this will help more fluid to be released.

TIP – Let the fluid drain for 10 to 15 minutes until it stops dripping, get out as much as you can.

Replace the drain plug, wipe of excess fluid from around the plug. Then put in 3 quarts of the cheap Mercon v Fluid for your first fill / flush.

TIP – Pour very slow, and hold the funnel so a small gap is visible, this will allow the fluid to pour down the fill spout easily. You also might want to place a rag around the spout.

Locate the Factory Trans / Oil cooler and remove the drivers side hose as pictured. Have your pan ready to catch some fluid from this hose.

Attach clear 3/8 I.D. tube to fitting so the fluid will drain out. If you get the correct size hose it will fit. I purchased 3/8th O.D. by mistake.

TIP – Make sure the hose is tight and the other end is inside the drain pan or container.

Start the car, press firmly on the brake. Shift into R,N,D and back to park 1 to 2 times. This will allow 3 quarts to pour out fast.

Replace hose and clamp, Repeat the last few steps if you want to flush out another 3 quarts. Now add in your last 3 quarts of ATF Mercon V fluid.

Replace ATF dipstick, make sure your drain plug and hoses are tight.Then start car and make sure there are no leaks, then back off the ramps or lift.

Here is the old ATF fluid, mine was done at 43k miles and was dark brown.

Enjoy your new Fluid & feel the difference.
